Flange: also known as a flange or collar flange. Flange is a part that connects between shaft and is used for connection between pipe ends; it is also useful for flanges on the inlet and outlet of equipment for connection between two equipment.
It is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding and so on.
Sekoinc has rich experience in Producing Special Alloys Foring Flanges.
